If you Mame that cabinet not many will help you. You'll be the scourge of arcade guys everywhere. To properly save it, since it might be 'tossed out' you must give it to a collector. There are plenty of people here that will *give* you something better/generic in exchange.
Unless you Mame it tastefully, of course. Don't want to mess with a arcade monitor? Why the heck not? Leave the controls stock, wire in a PC, and off you go.
